Information asymmetries can prevent markets from operating efficiently. An important example is the labor market, where employers face uncertainty about the productivity of job candidates. We examine theoretically and with laboratory experiments three key questions related to hiring via...

We examine the competitive effects of the vertical integration of gasoline refineries and retailers in the U.S. Adapting the first-order condition approach of static oligopoly games to the analysis of vertically related oligopolies, we develop a novel framework for directly evaluating the...

This paper discusses the rising profile of natural gas in global energy, factors constraining its further development, the gas contracting process, and the absence of a global market, which is analyzed in the context of the economic rent in the gas price and the opaque nature of gas contracts. A...

Nationalisation is high on the policy agenda in South Africa. This paper considers the case for nationalising the local mining sector from an evidence-based perspective. The relevant evidence is derived from theoretical considerations and related to the known features of the South African mining...

A model of global oil production is applied to study cartelization by OPEC countries. Writing out the shadow price on quota allocations so as to draw correspondence to coefficients of cooperation (Cyert et al. 1973), we examine the incentives that different OPEC members to collude. We find that...

Hypermarkets are large retail suppliers of general merchandise or grocery items that also sell gasoline, often at very low margins. Using panel data for 1998-2002, this paper estimates the impact of hypermarkets on average state-level retail gasoline prices. The empirical results suggest a...

We argue that repeated interaction and high-powered formal contracts can be either substitutes or complements, depending on the relative impact of repeated interaction on incentive problems and contracting costs. In the offshore drilling industry, we find that oil and gas companies are less...
